HOUSEHOLD PRESS FOR FRUITS AND VEGETABLES Filed Feb. 6, 1955 2Sheets-Sheet 2 Patented Nov. 26, 1935 HOUSEHOLD PRESS Eon FRUITS ANDVEGETABLES William Frank Kammer, .Wenatchee, Wash. Application February6, 1935, Serial No. 5,289

11 Claims. (Cl. 100-50) This invention relates to presses for expressingthe juices of fruits, vegetables and the like and the structure to bedescribed is an improvement upon the structure shown-in my Patent No.1,939,556, granted on December 12th, 1933.

The object of the present invention is to provide a structure operatedon the same general principles as the structure disclosed in my patentbut having certain improved functions thereover.

A further object is to provide a structure of this character wherein thepress head is'fixed and the cup moves upward against the press head toextract the juices from the vegetable or fruit, the press head being soconstructed and so related in diameter to the .cup that the discharge ofthe juices from the fruitor vegetable and from the cup will not beimpeded by either the press head or the crushed fruit.

A further object is to provide a structure: of

this character wherein the cup is provided with a hollow handle, oneportion of which constitutes a discharge duct, the bottom of the cupbeing so formed as to provide a runway for the juices, this runway beinginclined .downward toward the discharge duct.

A further object is to provide in a structure of this character, a fixedpress head supported upon a column, a cup movable upward against thepress head to crush the fruit and press the juices therefrom and areceptacle support moving upward with the cup so as to maintain aconstant relation to the discharged duct of the cup.

Another object is to provide improved means whereby hydraulic pressuremay be used for forcing the cup upward against the press head orretracting the cup or whereby the hydraulic pressure used may be gauged.

Other objects will appear in the course of the following description. i

My invention is illustrated in the accompanying drawings, wherein:----

Figure '1 is a side elevation of a fruit and vegetable press constructedin accordance with of Fi 3.

Referring to these drawings, l designates a base forming the bottom wallof a vertically extending cylinder ll, ;the top wall of which is 2!,carried upon a cup 22. 20f 'sheet metal.

designated l2. Extending upward from the base is a column l3 which,at'its upper end, is extended laterally and over the chamber II andcarries a press head, designated generally M.

The upper wall I2 of the chamber II is formed with a packing gland l5 ofany suitable construction and extending upward through this packinggland is a piston rod I6, which at its lower end, carries the pistonhead H. The circumference of this head is grooved to receive pistonrings I 8, these piston rings being of the character of: those used onautomobile pistons.

Detachably'engaged with the upper end of threaded engagement with theupper end of the piston rod l6. The-central portion of this head isprovided with; a recess 20, adapted to interlock with a downwardlyprojecting flanged stud This cup 22 is made The bottom of the cup isformedwith a central slightly depressed orconcave portion 23, adaptedtoform a seat for the fruit or other articles to be pressed. From thiscentral seatj23, the bottom of the cup extends 25 downward and radiallyoutward at 24 and the marginal-portion of the bottomadjacent theperipheral wall of the cup is formed with an annular depression 25,which extends entirely around the cup. At one point of its side wall,the cup, is provided with'the handle 26. This j handle being open at itscenter, as at 21, and the lower wall of this handle is formed to providea tothe contour of the bottom of the cup 22 so 40 as to provide a fullsupport for this cupthroughout the entire area of the bottom. The stud2! may be disengaged from the recess 20 by a predetermined rotation ofthe cup relative to the head l9, or, in other words, there is in effecta bayonet joint engagement between the cup and the head.

Attached to the head by any suitablemeans is a downwardly extendingskirt 29. It extends down around the body of the chamber ll. Immediatelybeneath the handle 26 of the cup, however, thisskirt extends outwardinstead of downward and is formed with the depressed portion 3E1 havinga discharge pipe 3| extending downward from this depressed portion.

The wall of the chamber is also formed with an outwardly extendingportion 32 which is depressed to conform to the depression 30 andreceive this depressed portion of the skirt and through this depressedor convex wall 32 of the chamber, the discharge pipe 3| passes. Thisdischarge pipe 3| telescopes into a discharge pipe 33, which extendsbelow the pipe 3|. Exteriorly of the depression 30, the skirt 29 isdownwardly extended, as at 34.

Extending across the depression 30 is perforated supporting plate 35upon which the receptacle 36 is adapted to rest. The perforations in theplate 35 are to permit any juices which might escape from the receptacleto drain downward through the pipes 3| and 33.

With this construction, when the piston I! is moved upward and the head|9 moved upward together with the cup 22, the receptacle support 3% willalso be moved upward and the pipe 3| will shift through the outer pipe33. As the piston l1 and head l9 are moved downward, of course thereceptacle support formed with the parts 3!! and 35 will also movedownward.

The press head I 4 is solid and has its lower surface made to conform tothe conformation of the bottom of the cup 22. Thus, the central portionof the press head l4 has a convex face 31 and from this central portion,the lower face of the press head |4 extends downward and outward, as at38. It will be noted that the press head has a diameter substantiallyless than the interior diameter of the cup 22 so that when the cup isbrought upward against the press head, the fruit Will not be socompressed as to be forced outward over the channel 25 and thus obstructthis channel but the fruit will be pressed downward against the bottomof the cup and all of the juices expressed therefrom.

Preferably the column I3 is provided with a duct 39 which extends fromthe lower end of the column and opens at its lower end into the chamberH, the duct extending upward through the column l3 and to a gauge 40,preferably disposed in a recess in the angularly extended end of thecolumn just above the press head l4. This is a pressure gauge and may beof any suitable character.

For the purpose of discharging liquid under pressure into the spaceabove the piston IT, to force the piston I! downward or into the spacebelow the piston, to force the piston upward, I provide the four-wayvalve casing designated 4|, and having a pipe extending therefromdesignated 42, which extends up through a. pushing 43, carried by thepiston IT. This four-way valve 4| has an inlet pipe 44 and an outletpipe 45, these pipes extending through the base I0 and the valve casing4| is also provided with an outlet 46 into the space below the pistonThus when the valve is turned in one position, water entering throughthe pipe 44 will be discharged into the space below the piston and causethe lifting of the piston, while water which may be above the pistonwill be forced out through the pipe 42 and the outlet pipe 45. This willraise the piston to carry the cup upward to bring the fruit intoengagement with the press head I4. After the fruit has been squeezedbetween the press head and the bottom .of the cup, the piston I7 is tobe moved downward and to this end the valve 41 within the valve body isturned so that water from the pipe 44 will pass upward through the pipe42 and water within the space below the piston will be dischargedthrough the openand the column 3. A convenient material for this purposeis cast iron.

While I have illustrated certain details of construction and certainarrangements of parts, I

do not wish to be limited to these details as the invention might beembodied in a number of different forms without departing from thespirit of the invention, as defined in the appended claims.

One of the chief advantages, due to the fact that the cup moves upwardagainst the press head, is that time can be saved in taking out the pulpand in putting in fresh fruit. Furthermore, this eliminates overheadstructure and makes a better balanced press and there is no tendency totop heaviness in my present design.

While I have described my press as being particularly designed for apress for vegetables and fruit, that is a household press, I do not wishto be limited to this use as it is obvious that the same principle canbe used in connection with a machine shop press by merely changing thecontour or character of the confronting faces of the head I9 and thehead l4 so that these heads will coact with each other to press thearticle between them.
